I did much of the publicity photography for a college. An assortment of 8x10 prints of an event would be submitted the next day on spec to the PR department. They took what they needed at $1 per print (this was decades ago) and I still have hundreds of rejects. This system was profitable for me and efficient for the PR department.
If I was Barry, I'd submit three finished prints to the client. If they are rejected, he will have three quality prints that should find a good home eventually. If they are accepted, the clients and intermediaries have good reason to appreciate his business style. There are other ways to conduct business, but not for me.
